Discontinuation of yaydl

If you're one of the few yaydl users out there, you might have noticed that I didn't put too much effort in the project recently. As I don't see any chance of maintaining yaydl in an appropriate way over the next months, I decided to discontinue the whole thing. Feel free to use the script as long as it works for you, but please don't email me any bug reports or the like. If you're looking for an alternative, I suggest you take a closer look at clive or youtube-dl.
